摘要：揭示一種香煙濾嘴，包含一多重區段濾嘴，能降低預定煙霧成分的程度。此濾嘴包括位於香煙嘴部末端的一纖維濾嘴栓塞、選擇性吸收材質製成的一區段及一般性吸收材質製成的一區段。選擇性吸收材質，例如酚甲醛樹脂矩陣，其表面被官能化具有主要及次要氨基群組，如此可以從香煙煙霧中去除特定的煙霧成分。一般性吸收材質，例如活性木炭，最好具有高表面積且能吸收煙霧成分而不會有高度的特異性。就結構上來說，纖維濾嘴栓塞、選擇性吸收區及一般性吸收區是一前一後地同軸排列。

摘要： A smoking article, such as a cigarette, includes, in one advantageous embodiment, a generally cylindrical, hollow tubular mouth section located in coaxial abutment to one end of the tobacco column of the cigarette. The wall of the mouth section is fabricated of an impermeable material. A plurality of grooves are formed in the periphery of the mouth section extending generally longitudinally thereof and being open to at least the mouth end of the mouth section. Air permeable tipping material circumferentially surrounds the mouth section and overlaps a portion of the tobacco column adjacent the mouth section. In a further embodiment of the present invention as discussed above, the tobacco column is two coaxially located tobacco sections with the tobacco section interfacing with the mouth section being of a different density than the other tobacco section. In yet a further embodiment of the present invention, the generally cylindrical, hollow tubular mouth section is formed with flow channels through the mouth section. Ventilation air openings are formed through the wall of the mouth section to provide for the flow of ventilating air into some of the flow channels. Air permeable tipping material circumferentially surrounds the mouth section and overlaps a portion of the tobacco column adjacent the mouth section, the grooves are organized into a plurality of groups, each group including a plurality of grooves to provide for the flow of ventilating air therethrough and through the ventilation air openings of the mouth section into the flow channels.

摘要： A ventilated mouthpiece adapted to be attached to a smoking article, such as a cigarette, includes a generally cylindrical core member of smoke and air impermeable material having a smoke inlet end and a mouth end. The smoke inlet end is to be placed in juxtaposition to one end of the tobacco column of the cigarette. The core member is formed with a plurality of smoke flow capillaries therethrough for delivering unfiltered smoke from the tobacco column to the mouth end of the core member, and at least one ventilation air flow channel which receives ambient ventilation air and delivers the ventilation air to the mouth end of the core member. The smoke outlets from the smoke flow capillaries at the mouth end of the core member are located at a further radial distance from the center of the core member than is the outlet from the at least one ventilation air flow channel.
